Existing in various forms since at least the Neolithic period, chewing gum has been made from many materials, including plants, grasses, and resins. Though the first commercial chewing gum was sold in the US in 1848, modern chewing gum was only developed in the 1860s, when a rubber substitute called chicle began being imported from Mexico. In 1869, after Thomas Adams's experiments with the natural latex, a man named William Semple filed for the first chewing gum patent. How is gum made today?
